It's mainly because Kwonwoo full power is too heavy. It's not that they're not allowed to be together, it's just Dowoon need some rest time from Kwonwoo. They've been living together for days and they also have sex. So ofc Dowoon gonna be spent, all his energy automatically got sucked by Kwonwoo
Besides, Dowoon is fine, Kwonwoo is just overreacting. He just can't be apart from Dowoon because of his anxiety. Also, Dowoon is quite durable you know, He'll sleep for hours and go back eating like a pig
It’s the difference in levels, the esper is too strong and it’s taking too much energy from the guide, if they were the same level then this wouldn’t be an issue. Because they imprinted, he’s taking energy just by being near him, which is why he didn’t want to get too close in the first place.
This is why when he lost his memories they were ok too, because he also lost part of his power.
I don't understand imprinting like the esper is supposed to be always near the guide because not other guide can help them but at the same time the esper cannot be touching or near the guide all the time because the guide is gonna be weak THIS IS SUCH A HASSLE
And I read this happened because of one side imprinting but how does that even work, I understand the mechanics of this in omegaverse cause of pheromones but in this case wth is going on, I'm lost
